Re: Is it possible to run rgrep in emacs on Win32?

[Evgeniy Dolzhenko]

Since my comment about this setup being dog slow went unnoticed I'd like 
to reiterate find+xargs+grep are really slow on Windows on just 
moderately large projects, so I'm looking for a solution to this? Is it 
switching to ack?

Maybe somebody will post an example config for recent Emacs/ack versions?

Cheers,
Ev
